The Summit Bivy is an advanced bivy sack system that uses DAC Featherlite aluminum poles to create a self-supporting canopy around the facial area. This allows better breathability and movement without added exposure to the elements.
This bivy is essentially like a sleeping bag with a miniature tent for just your head area. A fully enclosed sleeping bag is suffocating and dangerous, but being exposed to the elements can be a threat as well if the conditions are extreme. The Summit solves this problem with the unique tent/bivy like design by allowing an encapsulated area to protect your head without causing breathability issues.
Great for backpacking, camping (especially in cold, snowy climates), and emergency preparedness.
